In brief:
- What you give it: the idea to explain, who it's for, and how long it should be.
- What you get: a narrated explainer with captions, in the style you choose: motion graphics, illustrated or 3D story, a cartoon presenter or an AI avatar.
- Changes: ask in plain words, 5 credits each.
- Cost: 50 credits for a story or presenter explainer with voiceover included, or 45 for motion graphics with a voiceover. Each render is 10.
What is an AI explainer video maker?
An AI explainer video maker turns a written explanation into a short narrated video: it writes the script, records the voiceover, designs the scenes that illustrate each point and adds captions. You describe what needs explaining; you don't storyboard, record or animate anything yourself.
Which explainer style should you choose?
| Style | Best for | Voiceover |
|---|---|---|
| Motion graphics | How a product works, data, step-by-step processes | +10 credits |
| Illustrated story | A customer's problem and how it gets solved, told as a story | Included |
| 3D story | The same, with more depth and a premium look | Included |
| Cartoon presenter | A friendly host explaining a concept or reviewing a product | Included |
| AI avatar | A realistic person explaining to camera, with graphics around them | The presenter speaks |
If you're not sure, start with an illustrated story for an idea people need to understand, and motion graphics for a product people need to see.
How do you make an explainer with Relo?
- Pick a mode in the mode menu next to the chat box.
- Write the brief: what you're explaining, who's watching, the one thing they should remember, and the length.
- Watch the draft. Relo writes the script, voices it and builds the scenes.
- Ask for changes: "Slow down the second scene", "Use a simpler word than latency", "End on the sign-up link".
- Render in 16:9 for your website and YouTube, or 9:16 for social.
An example brief:
60-second explainer for Ledgerly, an invoicing app for freelancers. Audience: designers who hate chasing payments. Problem: invoices get paid late. Show how Ledgerly sends reminders automatically and how the freelancer gets paid. Warm, friendly tone. End with "Start free at ledgerly.app".
What makes an explainer work?
- One idea per video. If you need a second idea, make a second video.
- Problem first. Open with what the viewer struggles with, not with your company.
- Under two minutes. 60–90 seconds is enough for most explainers.
- Plain words. Write the way you'd say it out loud.
- Show, then tell. Every sentence of the script should have something on screen that shows it.
The AI avatar explainer guide covers scripts for presenter-led explainers in more detail.

No. Describe the idea, the audience and the one thing they should remember, and Relo writes it. You can also paste your own script.
Which style is best for an explainer?
An illustrated story for ideas people need to understand, motion graphics for products people need to see, and an AI avatar when a human face builds trust.

50 credits for an illustrated, 3D, stickman or presenter explainer with voiceover included, or 45 for motion graphics with a voiceover. Each render is 10 credits.
